The ability to per- form anterior only reconstruction requires mobility of the opposite column to achieve cor- rection, unless a combined approach is planned. Anterior cervical discectomy and fusion has limited focal correction, but when applied over multiple levels there is a cumulative ef- fect with a correction of approximately 6° per level. Partial or complete corpectomy has the ability to correct sagittal deformity as well as decompress the spinal canal when there is an- terior compression behind the vertebral body.

By Zachary Whipple Capstone Project Submitted to the Faculty of the Department of Physician Assistant Education of the University of the Pacific in partial fulfilment of the requirements for the degree of MASTER OF PHYSICIAN ASSISTANT STUDIES April 2020 Introduction End-stage ankle arthritis is a debilitating degenerative disease commonly located at the tibiotalar joint. The prevalence of symptomatic arthritis is about nine times lower than the rates associated with those of the knee or hip.1 Though less common than knee and hip arthritis, the US estimates greater than 50,000 new cases are reported each year.2 The most common etiology of ankle arthritis is post-traumatic pathology.

  • Differences Between Subtotal Corpectomy and Laminoplasty for Cervical Spondylotic Myelopathy
    Spinal Cord (2010) 48, 214–220 & 2010 International Spinal Cord Society All rights reserved 1362-4393/10 $32.00 www.nature.com/sc ORIGINAL ARTICLE Differences between subtotal corpectomy and laminoplasty for cervical spondylotic myelopathy S Shibuya1, S Komatsubara1, S Oka2, Y Kanda1, N Arima1 and T Yamamoto1 1Department of Orthopaedic Surgery, School of Medicine, Kagawa University, Kagawa, Japan and 2Oka Orthopaedic and Rehabilitation Clinic, Kagawa, Japan Objective: This study aimed to obtain guidelines for choosing between subtotal corpectomy (SC) and laminoplasty (LP) by analysing the surgical outcomes, radiological changes and problems associated with each surgical modality. Study Design: A retrospective analysis of two interventional case series. Setting: Department of Orthopaedic Surgery, Kagawa University, Japan. Methods: Subjects comprised 34 patients who underwent SC and 49 patients who underwent LP. SC was performed by high-speed drilling to remove vertebral bodies. Autologous strut bone grafting was used. LP was performed as an expansive open-door LP. The level of decompression was from C3 to C7. Clinical evaluations included recovery rate (RR), frequency of C5 root palsy after surgery, re-operation and axial pain. Radiographic assessments included sagittal cervical alignment and bone union. Results: Comparisons between the two groups showed no significant differences in age at surgery, preoperative factors, RR and frequency of C5 palsy. Progression of kyphotic changes, operation time and volumes of blood loss and blood transfusion were significantly greater in the SC (two- or three- level) group. Six patients in the SC group required additional surgery because of pseudoarthrosis, and four patients underwent re-operation because of adjacent level disc degeneration.

  • Procedure Coding in ICD-9-CM and ICD- 10-PCS
    Procedure Coding in ICD-9-CM and ICD- 10-PCS ICD-9-CM Volume 3 Procedures are classified in volume 3 of ICD-9-CM, and this section includes both an Alphabetic Index and a Tabular List. This volume follows the same format, organization and conventions as the classification of diseases in volumes 1 and 2. ICD-10-PCS ICD-10-PCS will replace volume 3 of ICD-9-CM. Unlike ICD-10-CM for diagnoses, which is similar in structure and format as the ICD-9-CM volumes 1 and 2, ICD-10-PCS is a completely different system. ICD-10-PCS has a multiaxial seven-character alphanumeric code structure providing unique codes for procedures. The table below gives a brief side-by-side comparison of ICD-9-CM and ICD-10-PCS. ICD-9-CM Volume3 ICD-10-PCS Follows ICD structure (designed for diagnosis Designed and developed to meet healthcare coding) needs for a procedure code system Codes available as a fixed or finite set in list form Codes constructed from flexible code components (values) using tables Codes are numeric Codes are alphanumeric Codes are 3-4 digits long All codes are seven characters long ICD-9-CM and ICD-10-PCS are used to code only hospital inpatient procedures. Hospital outpatient departments, other ambulatory facilities, and physician practices are required to use CPT and HCPCS to report procedures. ICD-9-CM Conventions in Volume 3 Code Also In volume 3, the phrase “code also” is a reminder to code additional procedures only when they have actually been performed.
